Very comprehensive set of features and at the time the profile of the wrist unit as opposed to the earlier Garmins was really good. "Out of the box" working was simple for the simple features but to get the best from the unit you need to spend time understanding the more complex features. Customer support from Polar.

The features are also its main weakness very complex and unless you are absoulutely certain you need all of them I would keep your cash and look elsewhere. In the short term 1-2 yrs the first thing that started to go was the transmission of data to the PC even with the POLAR recc unit. After 2 yrs the unit would not pick up HR(it has been returned twice and worked for a short time after each repair)In the end I lost patience with it so that was No date transfer no HR info and then the characters on the watch begun to go the LCD is failing though still readable. This unit is now used as a stopwatch/distance/speed unit with no HR.

This was my secong HRM. In the short term a good machine. I did not like the polar trg interface as I prefer my own log. Data transfer was inconsistent then failed altogether. HR failed. LCD has started to go. In the long term this has been a poor buy. How long should we expect these machines to last? @ £200+ longer than 5 yrs I would have thought.

It's a great product and with the V5 software you can do a lot back home at the desk.I use mine a lot but have had issues with the beeps, the speed at which the watch reacts to changes in my speed and how the 'off' period of intervals works
